Editor's note:The Virtual Telescope Project's planned live broadcast of Comet Pan-STARRS has been rescheduled for Saturday (from Friday) because of cloudy conditions. The observatory's free webcast will begin Saturday at 1 p.m. EDT.
An online observatory will broadcast live views of the Comet Pan-STARRS from Italy, weather permitting.
The Virtual Telescope Project in Ceccano, Italy, will webcast views of Comet Pan-STARRS beginning at 1 p.m. EDT Saturday. The comet is currently visible just after sunset to stargazers in the Northern Hemisphere, and can be seen low on the western horizon.
"We are so excited," astrophysicist Gianluca Masi, who runs the Virtual Telescope Project told Space.com in an email. "A lot of people are waiting for this event!"
The source webcast will also be available at the Virtual Telescope Project website.
Comet Pan-STARRS has been visible in the Northern Hemisphere evening sky since last week, though stargazers in the Southern Hemisphere were tracking the comet for months before it moved into the northern sky. The comet made its closest approach to the sun on Sunday, and was at its brightest at that time. [How to see Comet Pan-STARRS]
But the position and timing of Comet Pan-STARRS in the evening sky has made it a challenge for some stargazers to see. The best time to see the comet is shortly after sunset, when bright evening twilight can interfere with the comet's glow. A clear viewing area with no obstructions, such as buildings or trees, is vital.
Veteran astrophotographers Imelda Joson and Edwin Aguirre snapped photos of Comet Pan-STARRS from Horn Pond in Woburn, Mass., on Wednesday.
"Initially, the comet was difficult to spot with the naked eye or binoculars in bright twilight, but as the sky got darker, it became quite obvious," Joson and Aguirre told Space.com. The duo also occasionally writes space photography columns for Space.com.
"However, one has to know exactly where to look to find the comet. Some casual observers might be impressed by the comet's appearance, but others might get disappointed," Joson added. "It really depends on one's level of expectation, observing skills and the amount of light pollution at his or her observing site."
On Tuesday, Comet Pan-STARRS was visible near the moon, amazing stargazers around the world who had clear views and good weather. The comet is slowing moving higher in the night sky, but it will also get dimmer, NASA scientists have said.
NASA's Stereo-B sun observatory also captured a video of Comet Pan-STARRS with the Earth and planet Mercury this month.
"The comet should remain visible to the naked eye through the end of March," NASA officials said Thursday in a video update.
Comet Pan-STARRS is officially known as C/2011 L4 (PANSTARRS) and was discovered by a team of astronomers using the Panoramic Survey Telescope & Rapid Response System (Pan-STARRS) in Hawaii. The comet likely took millions of years to make its way into the inner solar system from the distant Oort Cloud at the edge of the solar system, but after this first swing around the sun it should settle into an 110,000-year orbit, scientists have said.
Pan-STARRS is one of several comets to grace the night sky in 2013. Earlier this year, Pan-STARRS and the Comet Lemmon were visible at the same time from the Southern Hemisphere.
In late November, the incoming sungrazer Comet ISON will make its closest approach to the sun. Comet ISON was discovered by amateur astronomers in Russia in September 2012 and could be a potentially dazzling "comet of the century" in November, but it could also fizzle out — it's too early to tell, NASA scientists have said.
